Overview

Here's a solution that's so simple, you'll wonder why it took so long to develop! The Clamp-It® replaces custom clamping jigs, acts as a third hand, and eliminates the need for long bulky clamps. Simply put, the Clamp-It® is a square you can clamp. In fact, you can even assemble a cabinet one corner at a time! Works with any joinery technique, from nails to hand cut dovetails.

It's ideal for every stage of construction, from assembling plywood cabinets to face frames and drawers. Clamp-It® is also perfect for framing decks and installing rails and balusters. Attach it to a work surface, and it becomes a right angle fixture for bench assembly. Clamp-It® is computer designed and manufactured from high impact, rigid polycarbonate to ensure strength and accuracy. Size of the Clamp-It® is 8" X 8" X 1 - 1/2".

Great for:

Drawer Assembly: Clamp-It® is designed for use on either the inside or outside of a corner, making it ideal for assembling drawers with lipped fronts.

Deck Rails: Use Clamp-It® to hold deck balusters at a perfect 90° angle while fastening.

Bench Jigs: Clamp-It® can be secured to any work surface to create a simple 90° assembly jig.

All these orders come from my husband. Since he's retired he has time to make repairs and new items in his workroom. He enjoys working with wood and uses clamps a lot so I was not surprised when he told me to order more. He has been pleased doing business with Rockler for several years.

Thought I would give Clamp-It Assembly Squares a try so I purchased two to use in my shop. I have a very large project to build and clamped the Clamp-it squares to upright 2x4s to act as a third hand. They worked so well that I have just ordered six more. They held everything squair and secure while I worked. I wish I had a set of these a long time ago they would have saved me a lot of time. Could not live without them now.

I bought 4 of these clamps thinking that I could use them in my business. Turns out not a one of them is actually square. They are about 1/32&quot; out of square in the length of the leg. They are worthless for use in a professional setting.

I bought a pair of these and a pair of the adjustable ones about 2006. Since then, I built 50 or so large frames for an artist who needed canvas stretcher frames from 5' x 5' to 12' x 7' (various sizes, by requirement). These squares were wonderful and the artist sold her paintings for $5 to $20 thousand. She told me she got compliments on the quality of the stretcher frames from quite a few customers. She moved away so I just use these for whatever I need them - they still work great!

I was quite disappointed in the Clamp-It Assembly Square. It is at least 1/32 out of square over the short 6&quot; length. This expands to a much larger error over a 28&quot; length of my cabinet. I will try to square up the Clamp-It but don't feel I should have needed to.

I cannot share the enthusiasm for the product with other contributors. I found that, yes, once you have the pieces clamped in place it is like having a third hand at least and an assistant at best. However, I find it very difficult to allign the pieces and apply the clamps in the first place. Maybe because I have two left hands but so far I have found the product more frustrating than helpful.

Very simple and quick to use in making a frame, one in each corner. I was able to dry fit and then release one side at a time to glue and Kreg screw together. Only a small amount of sanding needed afterward for seamless bonding

As several others have pointed out, these are molded and have ridges that interfere, in addition to not being square, possibly due to shrinkage while cooling. The internal bosses on the squares also make the clamping surfaces wavy. Those of you who gave these five stars, I wish you well with your projects. These are not professional grade.

I purchased 4 5&quot; and 4 8&quot; and they are fantastic! Extremely accurate, easy to use and save a lot of time. No more trial and error. With the Assembly Squares your glue-up is dead on the first time.

I bought 4 of these along with 8 of the 5&quot; clamps that go with them. While I haven't really used them for their intended purpose (I haven't made any boxes recently), they also work well as simple squares.The 5&quot; clamps however, are perhaps the most useful thing I have bought in a long time. I use them everywhere. Because they so light and small they are very easy to use. You might think the 5&quot; size is too small but you would be surprised by how often you can use these clamps.

These are like a second hand to me! I grab them whenever I'm building a box or shelf, and you know most of time that's all we're building anyway! I didn't get the clamps in the picture, due to other people's reviews, instead I got the Irwin quick grip minis and they work perfect with them, the mini grips are not strong enough for glue purpose, but are convenient and fit these well. I usually nail or screw with the glue so it's not a problem. These squares are solid, I dropped them a lot of times but they are unscathed. I bought two but may add more in the future. Highly recommended.

This is a real timesaver and dead-on accurate. I have used this for squaring bookcases and drawers when gluing. Once I clamp these into the corners, my project is square - everytime. No more trying to figure out why my project is out of square. A simple little tool that saved hours on my projects.

Awesome product! I will have to admit a bit awkward first time insuring use of groove on assembly square. If material being fitted is deeper than this thickness of square, you must place material below to insure groove is above pieces to fit. This is necessary to insure square only goes to end of each piece, and remains true 90 degrees. Quality of these pieces is excellent.

Everything all have said plus the nice thickness, the durable material and the the trueness of the angle. For me the thickness & size alone does it. Something you can realy grab and handle without the weight of steel!

I keep thinking up new ways to use these. Mine checked square enough for any wood work I do. Inside/outside corners, box assembly, clamped to sheetgoods a pair can hold it upright on a bench and I grab one for a quick check of "square" during assembly. I'd recommend them to friends, and do.

These are excellent. They are sturdy enough for their intended purpose, and a set of 4 of these from my local Rockler store got me out of a bind while assembling a large cabinet that needed &quot;help&quot; getting and staying square. Occasionally these have gone on sale and I'd buy 4 more for sure.&nbsp; For the problem they solved, still worth every penny.

The clamps purchased were of great quality for such little mighty mites. They are great when used along with the assembly square but are terrific for so many other small projects around the shop. Every shop should have a half a dozen or so on hand!

They're square. Bought some of these that came with the small bar clamps. Not so good. Difficult to attach and clamps are poor design. Got the newer corner clamping jigs and attached these squares and we have a winner!

This is one of those items that I have used workarounds in place of for many many years.

They were recently on sale for a couple of bucks off so I pulled the trigger and bought a pair.

I could not be happier with these beefy gadgets! Besides the obvious of holding case goods square while you glue, screw, and or nail they are quite useful for much more. A great square up for face frames and nonpareil for the simple task of holding my plate joiner square.

Thanks Rockler Staff!

And if the powers that be actually read this, thanks for sponsoring Laura Kampf, April Wilkerson, and others on YouTube.

Years ago (I think when Rockler first introduced them) I bought a pair to see if they might be useful. Were they ever! Sometime later I bought another pair (there ARE 4 corners to every project, right?). Just recently, they went on sale, so I stopped in for yet another pair-can't really have TOO many of these can you?
